Abstract
Background: Researches have shown that musculoskeletal disorders are among the most important occupational problems. Nowadays prevention of work-related musculoskeletal disorders is a necessity and national priority. This study was designed to identify the frequency of musculoskeletal disorders in food industry.
Methods: In a cross-sectional study, workers from 10 job categories in a food industry were selected. 50% of workers in each job category were randomly selected and at last 92 subjects entered the study. Nordic questionnaire was used to assess the frequency of work-related musculoskeletal complaints and QEC method was used for job analysis.
Results: Mean age of workers was 36.36 ± 8.50 (range: 23-55) years. Mean employment duration was 11.17 (range: 1-30) years. 21.7% of subjects had experienced pain and discomfort in at least one of the 4 areas (neck, shoulder, low back, and hand) in the last 12 months. Among all musculoskeletal disorders, those presented in low back and shoulder had a significant relationship with employment duration (p = 0.01).
Conclusion: This study showed that musculoskeletal disorders were more frequent in low back and hand regions.

Abstract
Introduction: Injury to muscles, tendons, ligaments, joints, nerves, blood vessels and soft tissues lead to musculoskeletal disorders. Type of work, the rate of repetition, severity and duration of work are risk factors for musculoskeletal disorders. Food plants contain repetitive motions so it is necessary to study the prevalence of musculoskeletal disorders in this study.
Methods: This study is a descriptive- analytical study to investigate the prevalence of musculoskeletal disorders in the one of the food manufacturing plans. Therefore, 200 workers in this industry were examined. In order to determine the prevalence of musculoskeletal disorders and symptoms Nordic questionnaire was used and to identify different body parts affected, body map questionnaire was used. Data was analyzed using SPSS (Ver. 18).
Results: The most common symptoms of patients were related to low back. Chi square test showed a significant relationship between sex and prevalence of symptoms in the areas of back, shoulder and
elbow of workers during the past 12 months (P <0.05). But in the neck, thighs, knees and feet we did not
see any significant difference.
Conclusion: Sex is a risk factor for development musculoskeletal disorders, so as the prevalence of symptoms in women was more than men.
